Peace of Mind when in Use and Instant Startup
Mobility
A solid-state laser light source provides virtually maintenance-free operation
until light source brightness is reduced.
4K Enhancement Technology to Project Even More
Information Crisply and Cleanly
• The high resolution of 4K enhancement technology allows you to display
more information than when using WUXGA or Full HD.
• 7,000 lm of high brightness realizes crisp, clean images even in bright
environments.
• The high color reproducibility of 3LCD technology allows you to experience
images rich with color.
• Digital image processing features such as super-resolution, detail
enhancement, noise reduction, and video adaptive gamma, allow you to
view crisp images with high visibility.
Quick and Easy Multi-projection Setup
• When using multiple projectors, you can attach an optional external camera
to automatically compensate for unevenness in brightness and color that
occur due to installation and the passage of time.
• Epson Projector Professional Tool allows you to quickly and easily setup
and adjust multiple projectors and perform advanced geometric correction.
• By allowing daisy-chain connections, you can project simultaneously
without having to use a distributor.
Install in a Variety of Environments
• A lightweight and compact housing provides a space-saving installation.
• A zoom of x1.6 or greater combined with lens shifting capability allows you
to avoid uneven ceilings and lighting when installing.
Simple and Easy Projection of Digital Billboards and
Storefront Productions
• Supports network updates for projects allowing you to change content with
ease.
• The 5V/2A USB power supply allows you to use the projector with an
external media player with only simple power wiring.
• The projector can play media directly from a USB memory drive.

fixed location. An optional ceiling mount is required when suspending the
projector from a ceiling.
You can also use a commercially available mount compatible with the VESA
Mounting Interface Standard (100 × 100 mm).
The projector can be installed at various angles. There is no vertical or
horizontal limit to how the projector can be installed.
Note the following points when selecting a projector location:
• Place the projector on a sturdy, level surface or install it using a compatible
mount.
• Leave plenty of space around and under the projector for ventilation, and
do not place it on top of or next to anything that could block the vents.
• Place the projector so it squarely faces the screen, not at an angle.

Warning
• You must install a ceiling mount when suspending the projector from a ceiling.
If you do not install the projector correctly, it could fall and cause damage or
injury.
• Do not use adhesives on the ceiling mount fixing points to prevent the screws
from loosening, or use lubricants, oils, or similar substances on the projector; the
projector case may crack causing it to fall from its ceiling mount. This could
cause serious injury to anyone under the ceiling mount and could damage the
projector.
• Failure to install the ceiling mount and projector may cause the projector to fall.
After installing the specific Epson mount that supports your projector, make
sure you secure the mount to all of the projector's ceiling mount fixing points.
Also, secure the projector and the mounts using wire that is strong enough to
hold their weight.
• Do not install the projector in a location subject to high levels of dust or
humidity, or in a location subject to smoke or steam. Otherwise, it could cause a
fire or electric shock to occur. The projector's case could also deteriorate and be
damaged causing the projector to fall from the mount.
Examples of environments that could cause the projector to fall due to case
deterioration
• Locations subject to excessive smoke or airborne oil particles, such as factories
or kitchens
• Locations containing volatile solvents or chemicals, such as factories or
laboratories
• Locations where the projector could be subjected to detergents or chemicals,
such as factories or kitchens
• Locations in which aroma oils are often used, such as relaxation rooms
• Near devices that produce excessive smoke, airborne oil particles, or foam at
events
• Locations near humidifiers
Warning
• Do not cover the projector's air intake or air exhaust vents. If the vents are
covered, the internal temperature could rise and cause a fire.
• Do not use or store the projector in locations where it will be subject to dust or
dirt. Otherwise, the quality of the projected image may decline. If the lens or air
filter gets dusty, it may result in a malfunction or fire.
• Do not install the projector on an unstable surface or in a location beyond the
weight specifications of the projector. Otherwise, it could fall or topple causing
an accident and injury.
• When installing the projector in a high position, take measures to prevent falling
by using wires to ensure safety in an emergency, such as an earthquake, and to
prevent accidents. If it is not installed correctly, it could fall causing an accident
and injury.
• Do not install in locations where salt damage could occur, or in locations subject
to corrosive gas such as sulphuric gas from hot springs. Otherwise, corrosion
could cause the projector to fall. It could also cause the projector to malfunction.
Attention
• If you are using the projector at altitudes above 1,500 m, set the High Altitude
Mode setting to On in the projector's menu to ensure the projector's internal
temperature is regulated properly.

• Try not to setup the projector in locations subject to high humidity and dust, or
in locations subject to smoke from fires or tobacco smoke.
